Concrete Garage Floors & Slabs in Toronto

Replace cracked or sloping garage floors, pour the slab for a new detached garage, or upgrade to a hard-trowel polished finish. Insured concrete contractor working across City of Toronto.

Why Toronto projects need a tailored approach

Toronto sits on Iroquois beach sand south of Bloor, lacustrine clay and till north, deep fill in older neighbourhoods, and the homes we work on are spread across neighbourhoods like Etobicoke, North York, Scarborough, Leaside, the Junction, Roncesvalles, the Beach and East York. Older Toronto lots have unknown fill, abandoned coal cellars, and clay lenses that we test-pit before quoting. Most central garages need underpinning checks before pouring new floors. Combined with Urban heat island slightly reduces frost penetration, but snow plowing and de-icer use is heavy, this changes how we design the slab and the base.

We pull permits where needed through City of Toronto Building (Toronto Building, City Hall and civic centres), so the work is documented and inspected, not buried under landscaping. Whether you are in postal code area M1 through M9, we serve every City of Toronto address with the same crew, the same supervisor, and the same written quote.

How we build a garage slab in Toronto


Our garage-slab process

  1. Step 1. Site visit and measurement. We confirm slab thickness, drainage direction, and any service penetrations (drains, conduit, EV charger feeds).
  2. Step 2. Demolition and removal of the failed slab. We protect the foundation wall, sill plate and door track during break-out.
  3. Step 3. Sub-grade preparation. Excavate to depth, compact, install Granular A in 100 mm lifts and re-compact, then place the vapour barrier and rebar mat.
  4. Step 4. Pour day. We pour at 32 MPa, screed to grade, bull-float, edge, and hard-trowel to a smooth finish suitable for epoxy or stain.
  5. Step 5. Saw-cutting and curing. Control joints saw-cut within 12 hours, then 7 days of moist curing or curing compound depending on weather.
  6. Step 6. Final walkthrough. We pull forms, clean the apron, and walk the slab with you before invoicing.
